La Unidad Académica Santa Cruz comprometida con el desarrollo científico al servicio de la sociedad boliviana cuenta con dos unidades de investigación en el área de salud: Instituto de investigación en Medicina conformado el año 2012, con más de 6 años de experiencia en proyectos de investigación en el área de enfermedades infecciosas y otros, y la carrea de Odontología, que cuanta con una gran cantidad de producción científica en torno a rehabilitación oral y otras temáticas abordadas desde la clínica odontológica. La participación en investigación de estudiantes de pre grado es fundamental, la misma se ve reflejada y conglomerada en dos sociedades científicas: Sociedad Científica de Estudiantes de Medicina y la Sociedad Científica de estudiantes de Odontología.

    Early identification of patients with Chagas disease at risk of developing cardiomyopathy using 2-D speckle tracking strain: Win, Miranda prediction of Chagas cardiomyopathy

    Background: Chagas disease is an endemic protozoan disease with high prevalence in Latin America. Of those infected, 20–30% will develop chronic Chagas cardiomyopathy (CCC) however, prediction using existing clinical criteria remains poor. In this study, we investigated the utility of left ventricular (LV) echocardiographic speckle-tracking global longitudinal strain (GLS) for early detection of CCC. Methods and results: 139 asymptomatic T. cruzi seropositive subjects with normal heart size and normal LV ejection fraction (EF) (stage A or B) were enrolled in this prospective observational study and underwent paired echocardiograms at baseline and 1-year follow-up. Progressors were participants classified as stage C or D at follow-up due to development of symptoms of heart failure, cardiomegaly, or decrease in LVEF. LV GLS was calculated as the average peak systolic strain of 16 LV segments. Measurements were compared between participants who progressed and did not progress by two-sample t-test, and the odds of progression assessed by multivariable logistic regression. Of the 139 participants, 69.8% were female, mean age 55.8 ± 12.5 years, with 12 (8.6%) progressing to Stage C or D at follow-up. Progressors tended to be older, male, with wider QRS duration. LV GLS was −19.0% in progressors vs. –22.4% in non-progressors at baseline, with 71% higher odds of progression per +1% of GLS (adjusted OR 1.71, 95% CI 1.20–2.44, p = 0.003). Conclusion: Baseline LV GLS in participants with CCC stage A or B was predictive of progression within 1-year and may guide timing of clinical follow-up and promote early detection or treatment.
